The signal's life-cycle has two stages: after creation its content could be filled by using standard list operations: ``sig.append()`` etc. After you call ``sig.freeze()`` the signal is *frozen*: adding, removing and dropping callbacks is forbidden. The only available operation is calling the previously registered callbacks by using ``await sig.send(data)``. For concrete usage examples see the `Signals <https://docs.aiohttp.org/en/stable/web_advanced.html#aiohttp-web-signals> section of the `Web Server Advanced <https://docs.aiohttp.org/en/stable/web_advanced.html>` chapter of the `aiohttp documentation`_. Installation ------------ :: $ pip install aiosignal Documentation ============= https://aiosignal.readthedocs.io/ License ======= ``aiosignal`` is offered under the Apache 2 license.
